West Virginia is a state in the Appalachian, Upland South, and Mid-Atlantic regions of the United States, bordered by Virginia on the southeast, Kentucky on the southwest, Ohio on the northwest, and Pennsylvania and Maryland on the northeast. The capital and largest city is Charleston. West Virginia broke away from Virginia during the American Civil War and was admitted to the Union as a separate state on June 20, 1863, and was a key Civil War "border state". It is one of only two states formed during the American Civil War (along with Nevada, which separated from Utah Territory) and is the only state to form by seceding from a Confederate state and one of three states to secede from another state (the others being Kentucky and Maine). The Census Bureau considers West Virginia part of the South because most of the state is south of the Mason-Dixon Line. The northern panhandle, however, extends adjacent to Pennsylvania and Ohio with the West Virginia city of Weirton on a parallel with Pittsburgh, while Bluefield is less than seventy miles from North Carolina. The unique position of West Virginia means that it is often included in a wide variety of geographical regions, including the Southeastern United States and even the Northeastern United States. Notably, it is the only state which entirely lies within the area served by the Appalachian Regional Commission, which is a common definition of "Appalachia". The state is noted for its great natural beauty, its historically significant logging and coal mining industries, and its labor history. It is also known for a wide range of outdoor recreational opportunities, including skiing, whitewater rafting, rock climbing, caving, fishing, hiking, mountain biking, and hunting.
